Ok guys, I'm looking ahead at some of the service maintenance that our xA's and xB's require. I'm a big DIY person and hope to perform all the services myself. Money is tight for me plus I know what exactly is being done to my Box. Not to mention you learn about your ride. Anyhow, I've done the oil change and looking at the next task which is to tighten the drive shaft bolt. Can someone please give some detailed information on this bolt as far as location and torque specs?

PS <> On my web site I am putting a "How-To" for all the services for the xA & xB. It may take a little while to get up, but hopefully by the end of the month I'll have most of it complete.

Anyone care to comment on inspection of the following:

1) How many ball joints are there? I know what they are just want to know how many there are to inspect??

2) Front differential oil. What is this stuff since tranny fluid is listed also??

3) Fuel lines and connections, fuel tank band and fuel tank vapor vent system hose??

4) How do you inspect the radiator core and condenser?

5) Steering gear box?

6) Steering linkage and boots?

7) brake linings / drums and brake pads / discs. How do you know if these are defective?

Things I already know how to inspect:
--ball joints and dust covers
--brake lines and hoses
--drive shaft boots
--engine coolant
--exahaust pipes and mountings
--fuel tank cap gasket
--tranny fluid

Get both volumes. Note the two different part numbers for xA and xB. Or maybe your local Toyota/Scion Parts dealer might be cheaper. Shop around from dealer to dealer though. Some could save you $$.

 

I don't really have the money to shell out for those 2 books. I would love to. I bought both for my civic: one for the civic and one for the Integra motor I had in my civic. I really don't have the funds to drop on the books now.

I wish someone would figure out how this works: https://www.scionlife.com/forums/viewtopic.php?t=6503

$10 for a manual would not be refused by me.

 

 

Yeah, ummmm. That's a nut that needs an impact guns touch! The nut is like 28mm I think. If youare in the area, I will take care of it. If you try to tighten it with socket and a rachet, you might hurt yourself. That nut is tight as it, if you want to tighten it go with an impact gun at a shop. :D

 

A toytota tech told me that the 5-speed DOES have a diferential- I have no way to back this up though- any other tech on here have a clue?

 

That would be the 30mm 12pt nut. Takes a special impact socket.

Let me just say never in my history of working for Toyota have I ever heard you had to tighten this nut. We never do it on 15k services. The nut is crushed once it is tightened so that it can't move. I almost find the idea of tightening it to be absurd.

 

Ok guys. One saying it's a 28mm the other a 30mm 12pt. crushed nut. Just blast it with a impact gun doesn't cut it. If this is true about being a crushed nut, why would Toyota have you re-tighten this nut every 15k. It does not say to check, but retighten the nut. A 28mm or 30mm nut is probably torqued over 110ft/lbs which IMO will NEVER come loose.

Does anyone know where this is located on the vehicle? Would like to get a look myself.

Thanks!

 

Its most definitely a 30mm 12pt, all the new Toyota cars use that special size. The old cars were 30mm regular nut with a cotter pin to keep it from moving. The new ones are 12pt and have a part crushed in so it can't move, same as Honda ones.

 

That could be. I was just thinkning that a FWD car, has a transaxel. So it takes the place of what a old drive shaft-diferential set up was. So I guess the diferential in this case, could be looked at as the tranny itself? or maybe its even in the tranny case. :oops:

 

Every production road car (with four wheels) has a differential. Although in front wheel drive cars it is usually in the transaxle, not a separate housing like rear wheel drives. I believe in the Scion the automatic transmission uses the ATF for lubricant, and the manual a gear lube, not sure though.

Good luck.

 

This is true. Autos use Toyota Type T-IV ATF and manuals use 75W-90 gear oil.

The differential is inside of the tranny case right where the axles go into the transmission housing.

 

Thats right! Also some other toyota trannys have the differential fluid serperate from the tranny.

Thats the size, and yes it is a 12point socket. Even if we did tighten the nut, it won;t move. Leave it alone and stop being a book worm. If it ain't broke don't fix it! :twisted:

 

^ What he said.

 

"Thats right! Also some other toyota trannys have the differential fluid serperate from the tranny. "



That was the old 4 cylinder 5S-FE Camrys that were like that.

 

So has anyone found this bolt yet? What does the mechanic at the dealer say?

 

i just took my car in for 15k service... my dealer claims it doesn't exist... and only needs to be done on rwd cars.

 

great info here

 

its probably refering to the axle nut. which is located in the hub. take your wheels off, and its the big 12 point 30 mm nut

 

Actually, I presume you read this in the "passport to maintainnce" book, and this is a book that hasn't been updated properly. The "driveshaft" in question only applies to Previa vans. It is the SADD shaft that spans from the engines crankshaft to the accessories located in the front of the van (ps pump, ac compresser, alternator, and\ or supercharger). It sounded like a good idea when the Previa was new, but in practice, I have never seen one loosen at any mileage. Don't worry.
